IMPROVEMENT IN REVERSIBLE ANVILS.

Specification forming part of Letters Patent No. 152,35l, dated June 23,.1874; application filed April l, 1874.

To all whom it may concern:

Beit known that I, BENJAMIN A. ELLIsoN, of Exeter, of the coun-ty ot'Rockingham and State of New Hampshire, have invented an Improved anduseful Reversible Swage-Block or Anvil; and do hereby declare the saineto beully described in the following specification and represented inthe accompanying drawings, of which- Figure l is'a front elevation, Fig.2 a top view, Fig. 3 a transverse section, and Fig. 4 an end elevation,ot' the swage-block and its supporting-frame.

In such drawings, A denotes a block of metal, in the form of arectangular prism, rabbeted along one edge, as shown at c, and havingtwo journals, b b', projecting' from its opposite ends. Furthermore, theblock has a series of swagc notches or recesses, c or el, made in eachof its opposite edges, such varying in width and depth, as occasion mayrequire. It also has another series of swage recesses or notches, c,leading from the rabbet, as shown. In other words, the rabbeted edge isprovided with two series of such notches, the lowermost ot' which areclosed at their inner ends, such closing of them being convenient forfinishing the end ot' a bar during the process of swaging it. The rabbetalso causes the notches of one series to be e11- tirely above those otthe other, with a space or distance between the two series, suchenabling any one of the upper series to be used for some kinds of workor articles which could not be swaged by it were it on a level with thenotches of the other series. One of the journals is nicked or slitteddiametrically across its end, with two slots, fg, at right an gles toeach other, such being to receive a spring-latch, B, fixed to the end ofthe supporting-frame C of the swage-block, and arr. nged with it and theswage-block in manner as shown. Furthermore, the swageblock also has aseries of holes, h, made in or through it transversely from one or bothsides of it, such holes being what may be termed punchholes,77 as theyenable the block to be used in supporting a plate or bar while beingpunched, the bar or plate resting upon the block and over one of theholes, so that the part separated by the punch may be driven through thehole.

'llhe block may be revolved in its frame so as to bring either edge orside of the block uppermost, as occasion may require, the block beingheld in either ot its four lpositions by the spring-latch, and one ofthe slits for its reception.

A swageblock so made is very useful for blacksiniths, especially in themaking of nuts or other forged articles of metal for carriages.

The block may be made without the rabbet, and with but one set ofnotches in each of its opposite edges; but it will not be so exltensively useful as when it is connected with the rabbet, and two rangesof notches in one edge, disposed as represented.

I do not claim a rotary swage 'made as described in the Patent No.88,125, as my swage -is not a circular block with swage-notches formedin its periphery in the direction of its axis, my swage being arectangular block, having the notches in its opposite edges, and each ina direction at right angles to the axis ot' motion, or ot' the journalsot the block. This enables me to bring all ot' one range ot' notches inone horizontal line, and avoids the necessity of turning the blockpreparatory to the use oi' each notch.

I claim- 1. A rotary swage-block having not only a series ofpunch-holes, h, made in or through it laterally from one or both sidesof it, but provided with pivots or journals b b at its oppositeends, andtwo series of notches, c d, arranged in its opposite edges, all beingsubstantially as described.

2. A rotaryswage-block, not only rabbeted on one edge, and thereprovided with two series of swage-notchcs, c c, all substantially asrepresented, but provided with a series of swage-notches, d, in itsother edge, and two journals, b b', projecting from its ends, all beingessentially as specified.

BENJAMIN A. ELLISON.
